我无法在路径下方设置TESSDATA_PREFIX环境变量设置为"tessdata"目录的父目录。

请保持将数据文件转移到tessdata文件夹中，并遵循以下代码：

import net.sourceforge.tess4j.Tesseract;
import net.sourceforge.tess4j.TesseractException;

 public class OCR_POC {

 public static void main(String[] args) throws TesseractException {

String inputFilePath ="F:/my_documents/issues.pdf";
Tesseract   tesseract = new Tesseract();
tesseract.setDatapath("F:/Tesseract/tessdata/");
//tesseract.setLanguage("chi_sim");
//tesseract.setLanguage("eng");// english is default langauge
String  fullText= tesseract.doOCR(new File (inputFilePath));
System.out.println("Full text : "+fullText);

 }
}

pom.xml的Maven存储库：
